Proteomic Analyses in COVID-19-Associated Secondary Hemophagocytic Lymphohistiocytosis.
Crit Care Explor
February 2025
Center for Fundamental Immunology, Benaroya Research Institute, Seattle, WA.
Context: COVID-19 has been associated with features of a cytokine storm syndrome with some patients sharing features with the hyperinflammatory disorder, secondary hemophagocytic lymphohistiocytosis (sHLH).
Hypothesis: We hypothesized that proteins associated with sHLH from other causes will be associated with COVID-sHLH and that subjects with fatal COVID-sHLH would have defects in immune-related pathways.
Methods And Models: We identified two cohorts of adult patients presenting with COVID-19 at two tertiary care hospitals in Seattle, Washington in 2020 and 2021.
The Diagnostic Utility of Host RNA Biosignatures in Adult Patients With Sepsis: A Systematic Review and Meta-Analysis.
Crit Care Explor
February 2025
Oxford Vaccine Group, Department of Paediatrics, University of Oxford, Oxford, United Kingdom.
Objectives: Sepsis is a life-threatening medical emergency, with a profound healthcare burden globally. Its pathophysiology is complex, heterogeneous and temporally dynamic, making diagnosis challenging. Medical management is predicated on early diagnosis and timely intervention.

Ir J Med Sci
January 2025
Department of Clinical Microbiology, Children's Health Ireland at Temple Street Children's University Hospital, Dublin 1, Ireland.
Background: Lab users should display an understanding of microbiology tests and avoid inappropriate requests which may yield negative clinical consequences. Our research addressed diagnostic stewardship education and the perspectives of paediatric hospital doctors on their (1) self-perceived knowledge, (2) motivators for test ordering, (3) proposed educational interventions and (4) preferred teaching modalities.
Methods: An anonymous, mixed-methods, 34-item online questionnaire was distributed to paediatric doctors across three Irish hospital sites from March to May 2023.
Mitochondria Express Functional Signaling Ligand-Binding Receptors that Regulate their Biological Responses - the Novel Role of Mitochondria as Stress-Response Sentinels.
Stem Cell Rev Rep
January 2025
Department of Regenerative Medicine, Warsaw Medical University, Warsaw, Poland.
Evidence accumulated mitochondria, as the "powerplants of the cell," express several functional receptors for external ligands that modify their function and regulate cell biology. This review sheds new light on the role of these organelles in sensing external stimuli to facilitate energy production for cellular needs. This is possible because mitochondria express some receptors on their membranes that are responsible for their autonomous responses.

Sports Med
January 2025
Department of Sport Science and Physical Education, Faculty of Health and Sport Sciences, University of Agder, Kristiansand, Norway.
Background: Endurance athletes tend to accumulate large training volumes, the majority of which are performed at a low intensity and a smaller portion at moderate and high intensity. However, different training intensity distributions (TID) are employed to maximize physiological and performance adaptations.
Objective: The objective of this study was to conduct a systematic review and network meta-analysis of individual participant data to compare the effect of different TID models on maximal oxygen uptake (VO) and time-trial (TT) performance in endurance-trained athletes.
